    I have just changed the oil on my 2008 A150 and the filter (Mahle) was supplied with 2 rubber O-rings, the large one for the outside of the canister , and a smaller one.

    The old filter only seems to have the one large O-ring on it. I cannot see where the new one would fit and it is too big to be for the dipstick.

    Anybody any ideas please??

    Well, this is a first for me, answering my own question ;)

    Visited my local independent today, who advised that the second o-ring is for the extended plastic 'arm', for want of a better term, that protrudes through the centre of the filter, as per the W168. Not all have them.

    Mine has a metal spring in the centre of the filter housing, which the filter then fits over - and this doesn't need the second o-ring.

    Updated for info. of others.

    Hi There,
    Yours didn't also have a plastic 'top hat' plug in the end of the filter element did it ? I have just helped a colleague do an oil / filter change on his A150 and he had this plug in th old filter along with a sprung centre spigot similar (or indeed exactly) as you describe
